DETAILED DESCRIPTION

The following embodiments describe systems and methods for dwell time based advertising. It will be obvious, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the present invention.

In the present disclosure, methods and systems are described for using article-level (or page-level) dwell time, or user time spent, for pricing both guaranteed delivery (GD) display ads contracts and non-guaranteed delivery (NGD) display ads contracts in online display advertising. Methods and systems for determining dwell time are provided with reference to U.S. application Ser. No. 13/843,433, filed Mar. 15, 2013, entitled “Display Time of a Web Page,” and U.S. application Ser. No. 13/843,504, filed Mar. 15, 2013, entitled “Page Personalization Based on Article Display Time,” the disclosures of which are incorporated by reference.

Broadly speaking, systems and methods in accordance with the present disclosure leverage article-level dwell time information for various aspects of display advertising. Dwell time information provides a more accurate and fine-grained understanding of user engagement than conventional click or action-based measures of user engagement. Therefore, its application to various advertising models as discussed in further detail below serves to improve efficiencies of the display advertising process. Compared with conventional methods and systems for display advertising, methods and systems in accordance with the present invention can provide improved fairness to both publishers and advertisers.

FIG. 1 illustrates a system for displaying ads to a user, in accordance with an embodiment of the invention. One or more publishers 100 provide content that is stored in a content storage 102. One ore more advertisers 106 provide advertisements (ads) that are stored in an ad storage 104. Broadly speaking, when a user 120 requests content for display on a user device 118, the content can be retrieved and displayed on the user device 118 with selected advertisements. In one embodiment, the user request for content may be defined by the user navigating to a web page or web site via an application running on the user device 118, such as a web browser application. The browser generates a request for the web page that is transmitted over a network 116 to a web server 114. The web server 114 is configured to retrieve content and advertising that define the web page for delivery to the user device 118 in response to the request.

In one embodiment, a content selection module 108 is configured to select content from the content storage 102 for retrieval and delivery to the user device 118. It will be appreciated that the selection of content can be based on a variety of factors, including but not limited to the following: recency, time of day, geo-location of the user, popularity, related social network activity, etc. Additionally, content may be selected based on a profile of the user, which may be defined in a user data storage 122, and may include various information about the user, such as the following: age, gender, residence/location, nationality, income, content preferences (explicit or determined based on prior activity), content consumption history, browsing history, etc.

An ad selection module 110 is configured to select advertisements for display to the user. The advertisements may be selected based on characteristics of the content and/or the user (e.g. defined by a content profile or a user profile). As discussed in further detail below with respect to both guaranteed delivery (GD) and non-guaranteed delivery (NGD) markets, a given advertisement may have a specified target, defined by one or more target parameters, such as characteristics of content or characteristics of a target user. Thus, when content is selected for presentation to a particular user, an advertisement whose target parameters match that of the content and/or the user (e.g. match characteristics or profiles of the content and/or user) may be selected for presentation with the selected content to the user. In the case of an NGD advertisement scheme, an auction module 112 is configured to perform an auction to determine which NGD advertisement to select for presentation. After selection of content and advertisements, the web server 114 transmits the selected content and advertising to the user device 118 for rendering on the user device 118.

Though specific embodiments are described herein with reference to web pages displayed in a web browser, it will be appreciated that the concepts and principles discussed herein may readily be applied to any type of system supporting display advertising, including various kinds of applications or apps defined for various kinds of hardware platforms (e.g. mobile devices, televisions, etc.).

In the current guaranteed delivery (GD) advertising market, advertisers purchase contracts that typically specify a target user group (e.g., females in California who visit fashion pages), a future duration for the contract (e.g., January 2013 to March 2013), and the number of user visits (or the number of page impressions) they are interested in obtaining (e.g., 100 million). Web publishers typically guarantee these contracts months in advance of the delivery date. GD contracts can be complex, and the terms of guaranteed contracts are most commonly decided through manual negotiations between a publisher (e.g. a sales representative representing the publisher) and an advertiser (e.g. a media-buyer representing the advertiser). The publisher may attempt to offer a combination of available products that best fits the advertiser's needs while also extracting the maximum possible revenue from the advertiser for the user visits sold (e.g., by marking up the price or offering discounts to close a sale, as appropriate).

In a typical CPM (cost per impression, or cost per thousand impressions) based GD contract, it is important to accurately estimate the true market value of user visits, so that contract negotiations can be effective and fair for both publishers and advertisers. However, negotiations of conventional CPM-based GD contracts are often predicated on the following assumptions: (1) advertisers assume that each visiting user interacts effectively with the visited page long enough to view the displayed ads; (2) publishers assume that each impression (or visit) leads to the same exposure of the ads and thus each impression is sold equally with the same price.

However, important user engagement information, including page-level dwell time that can be used to differentiate user engagement for each visit/impression, and whether a given user's focus is on each shown impression, are missing for purposes of determining pricing fairly and effectively for both publishers/advertisers. Without such information, estimating the true market value of each individual user visit becomes quite challenging. Hence, accurately measuring both the market value of each user visit (impression) for publishers, and the advertising effectiveness for advertisers is difficult based on the conventional CPM-based pricing model. For these reasons, advertisers generally prefer CPC (cost per click) or CPA (cost per action) pricing models, while publishers have practically no other reasonably fair models to choose from besides a CPM pricing model. (It is of course noted that publishers may or may not prefer a CPM-based model because it does not measure the true market value of each individual impression (which may produce different levels of user engagement).)

Accordingly, embodiments of the present invention provide for a page-level dwell-time based pricing model for GD contracts. In the dwell-time based pricing model, similar to the conventional CPM-based pricing model, advertisers can purchase contracts that specify a target user audience and a future duration for the contract. However, unlike the conventional CPM-based pricing model, advertisers pay for the total user time spent on page impressions they are interested in obtaining (e.g., 20 thousand hours), and Web publishers guarantee these contracts in advance of the delivery date. The dwell-time based pricing model directly leverages page-level user engagement information for pricing a display advertising contract, and guarantees that each user is exposed to the ad(s) for a specified time that advertisers are interested in procuring (which is not the case in the CPM-based pricing model because of the complex environment of browsers/tabs). Therefore, a dwell-time based pricing model can more accurately reflect the true expected market value of each publisher impression, and thereby facilitate fair and effective contract pricing for both publishers and advertisers.

In accordance with some embodiments, it is possible to achieve better pricing of a GD contract by modifying a CPM-based pricing model in the following approaches: (1) each impression (or each user visit) can be weighted by the dwell-time of each user visit; or (2) the CPM can be replaced in the pricing model with a cost per given time unit (e.g. seconds or minutes or hours).

FIG. 2A illustrates a method for performing guaranteed delivery of display advertising weighted by time, in accordance with an embodiment of the invention. At operation 200, a display ad is selected and presented to a user. The display ad has a guaranteed delivery amount associated with it. In one embodiment, the guaranteed delivery amount is defined by a number of impressions. It will be appreciated that the display ad may be selected from a plurality of ads for presentation at a given opportunity based on various factors. For example, in the context of a web page, the display ad may be selected for display based on predefined target parameters matching characteristics of the content shown on the web page and/or a profile of the user viewing the web page. At operation 202, the dwell time of the presentation of the ad is measured. That is, the amount of time that the user viewed or was exposed to the ad during that particular presentation of the ad (e.g. on a web page) is measured and recorded. At operation 204, a record of that particular presentation of the ad is recorded as an impression weighted by the measured dwell time of the presentation. At operation 206, an aggregate (e.g. a sum) of weighted impressions for the advertisement is determined. The aggregate of weighted impressions includes that described above along with other weighted impressions previously recorded for the advertisement. At method operation 208, the aggregate of weighted impressions is compared against the guaranteed delivery amount defined for the advertisement to determine a level of performance of the guaranteed delivery amount for the advertisement.

FIG. 2B illustrates a method for performing dwell time-based guaranteed delivery of display advertising, in accordance with an embodiment of the invention. At operation 210, a display ad is selected and presented to a user. By way of example, the display ad may be presented in conjunction with content via a display context such as a web page or mobile application. The display ad has a guaranteed presentation amount that defines a total amount of (dwell) time that the display ad is to be exposed to users. It is noted that the total amount of time is defined by time that the display ad is actually presented to users (as opposed to a broader time period during which the display ad may be shown, which may also be predefined for the display ad). At method operation 212, the dwell time of the presentation of display ad is measured. At operation 214, the dwell times for the display ad are aggregated, including the measured dwell time of the instant presentation as well as measured dwell times of prior presentations of the display ad. At method operation 216, a level of contract fulfillment is determined by comparing the aggregate dwell time for the advertisement against the guaranteed presentation amount.

It will be appreciated that the use of dwell time as a measurement of user engagement can also facilitate new advertising methods. For example, it is possible to show multiple advertisements during the same impression and measure the dwell time of each advertisement. With reference to FIG. 2C, a web page is shown having swappable advertisements, in accordance with an embodiment of the invention. The web page 220 in the illustrated embodiment includes a content location 222 and an advertisement location 224. Any of various kinds of content may be presented in the content location 222; and an advertisement can be selected for presentation at the advertisement location 224. Furthermore, during a single impression of the web page 220, multiple advertisements may be shown in the advertisement location 224. For example, during a first time period, an advertisement 226 may be presented in the advertisement location 224, and during a second time period a different advertisement 228 may be presented in the advertisement location 224. Thus, an advertisement may be swapped out for a new advertisement during the same impression of the web page. Though in the illustrated embodiment, two advertisements are shown, it will be appreciated that any number of advertisements may be swapped for each other and displayed during a single impression of the web page 220.

In some embodiments, the advertisements which are swapped for each other may be from the same advertiser. This can be desirable as it allows an advertiser to show multiple advertisements during the same impression. The advertiser may thus present different options to a user and thereby improve the chances that a user will engage with one of the advertisements in some manner. The act of changing advertisements for a given advertisement location may also draw the attention of the user to the new advertisement, thereby improving user engagement. Furthermore, for a single impression, the advertiser is able to present different types of advertisements and may therefore better understand a given user based on their reactions to the advertisements with fewer impressions.

In other embodiments, the advertisements which are swapped for each other may be from different advertisers. In this manner, the publisher is able to accommodate more advertisements from different advertisers for a given impression. The publisher may increase revenue per impression as multiple advertisements are shown for a given impression. Also, the publisher is able to accommodate a higher number of GD contracts for a given time period, as a single impression may count towards multiple advertisements (regardless of whether advertisements shown during an impression are from the same or different advertisers).

It will be appreciated that a first advertisement may be displayed for a predefined time period before it is swapped out for a second advertisement presented at the same location. A timer can be configured to determine when the predefined time period has elapsed. The predefined time period thus defines a maximum dwell time per impression for a given advertisement. It will be appreciated that different advertisements may have different predefined time periods (or maximum dwell times per impression) associated therewith.

By way of example, Bharadwaj et al., (Bharadwaj et al., Pricing Guaranteed Contracts in Online Display Advertising, CIKM 2010, which is incorporated by reference herein) have explored how to better estimate the true expected market value of each impression for pricing a GD contract. Their approach uses historical sales prices that are negotiated between a sales person and an advertiser, and the individual user visits that have been obtained under each contract to compute the expected market value/price of the individual user visits for the new GD contract. One of their algorithms (called WAP) computes the value of each user visit in the new contract as the weighted average of the prices (per user visit) of eligible historical contracts.

However, in a pricing model applying dwell-time data, it is possible to compute the expected market value/price of each time unit (e.g. seconds, minutes, or hours) of exposure of publisher pages/websites as the weighted average of the prices (per time unit) of eligible historical contracts. Accordingly, research results on CPM-based GD advertising models can be leveraged for determining the dwell-time based pricing model. By leveraging both dwell-time based user engagement information and existing research, it is possible to more accurately estimate the price of online advertising contracts (products) for both GD and NGD (non-guaranteed delivery) markets.

In contrast to the GD market, Non-Guaranteed Delivery (NGD) advertising defines a spot market where advertisers can buy ad impressions one at a time. Under an NGD mechanism, every time a user loads a web page with an ad slot, an impression opportunity to display an ad is defined. An auction is run among the ads that match the targeting specifications of that particular opportunity and an ad is chosen for display in the ad slot. One example of an NGD system is the Right Media Exchange (RMX) system for NGD contracts. At present, the RMX system handles more than 10 billion NGD transactions per day, with each transaction involving an auction for one impression opportunity and its matching advertising campaigns.

In contrast to the conventional CPM-based GD market, the NGD markets offer advertisers a wider range of payment models. Advertisers can choose to pay per impression (commonly known as a cost-per-impression (CPM) model). They can also choose to pay per click (commonly known as a cost-per-click (CPC) model), or pay per conversion/action (commonly known as a cost-per-conversion/action (CPA) model). These later payment methods may be desirable for the advertiser because an ad impression may not ultimately lead to a desired action on the part of the user, such as a visit to the advertiser's website or a product purchase. In the CPC model, the advertiser will not be charged unless the user clicks on their ad. The CPA model further reduces the risk for the advertiser by allowing the advertiser to pay only when the user takes an action that is of interest to them. Advertisers have control over the definition of these conversion actions. Exemplary actions include but are not limited to the following: subscribing to an email list, registering an account, adding an item to a shopping cart, or making a purchase.

FIG. 3 illustrates a process for performing an NGD advertising auction, in accordance with an embodiment of the invention. As shown, Advertisers A, B, C, and D submit respective bids A, B, C, and D for their respective advertisements. In the illustrated embodiments, the Advertiser A submits a CPM bid; Advertiser B submits a CPC bid; and Advertiser C submits a CPA bid.

In the NGD market, where advertisers with different payment types will compete for the same ad slot, an auction mechanism can be configured to convert bids that are in different payment models to a common base. Expected cost per impression (eCPM) is a widely utilized choice for such a common base. For CPM ads, the expected price per impression (eCPM) would be the same as the bid for that impression. For ads that are defined as pay per click (CPC) or pay per conversion (CPA), the eCPM will depend on the expected click or conversion rate for a given impression. More precisely, for a CPC ad, the eCPM can be expressed as the following: eCPM(CPC)=p(click|impression,ad)*bid; where p(click|impression,ad) is the probability that an impression will result in an ad click. For a CPA ad, the eCPM can be expressed as follows: eCPM(CPA)=p(conversion|impression,ad)*bid; where p(conversion|impression,ad) is the probability that an impression will lead the user to take the action(s) that constitutes a conversion for that advertiser. For more information, reference may be made to Rosales, et al., Post-Click Conversion Modeling and Analysis for Non-Guaranteed Delivery Display Advertising, WSDM 2012, and to R. McAfee, The Design of Advertising Exchanges, Rev Ind Organ, 2011, 39:169-185, which are herein incorporated by reference.

Thus, with continued reference to FIG. 3, the eCPM for Advertiser A's ad is equal to bid A, as bid A is a CPM bid. Whereas, the eCPM for Advertiser B's ad is the probability that an impression will result in an ad click multiplied by the bid B, which is a CPC bid. And the eCPM for Advertiser C's ad is the probability that an impression will result in the conversion action set for the ad multiplied by the bid C, which is a CPA bid.

However, it is noted that user engagement information for a given impression is not accounted for by conventional NGD payment models. Advertisers who choose a CPM pricing scheme in an NGD market are often more interested in building brand awareness where “getting the message out” is the goal. Information about page-level user timespent can accurately measure the exposure of the ads to the targeted audience. However, the conventional CPM-based approach does not account for this important information. Therefore, a Cost Per Time Unit (CPTU) (e.g. minutes/hours/days) payment method for the NGD market is herein presented. That is, an NGD contract can be based on how much time users spend on each publisher's web pages (time spent on impressions) where the ads are shown. In the illustrated embodiment, an additional Advertiser D is shown having submitted a CPTU bid for its advertisement.

Accordingly, a family of expected CPTU (eCPTU) values can be computed for CPC and CPA models so that auctions for an NGD spot market can still run based on existing pricing models. More precisely, eCPTU(CPC)=p(click|timespent on an impression,ad)*bid and eCPTU(CPA)=p(conversion|timespent on an impression,ad)*bid, where p(click|timespent on an impression,ad) is the probability that an impression will result in an ad click after the user is exposed to the impression for a given unit of time, and p(conversion|timespent on an impression,ad) is the probability that an impression will lead the user to take the actions that constitute a conversion for that advertiser after the user is exposed to the impression for a given unit of time. It is also possible to compute eCPTU for a CPM based campaign, that is eCPTU(CPM)=bid/(average timespent per impression*1000), wherein the bid is per thousand impressions. Using CPTU and eCPTU together, an auction can be run based on fine-granular user engagement time unit information as opposed to the impression-based approach.

Thus, with continued reference to FIG. 3, the eCPTU for Advertiser A's ad is bid A divided by one thousand (assuming bid A is a CPM bid per thousand impressions), further divided by the average dwell time per impression. The eCPTU for Advertiser B's ad is the probability that an impression will result in an ad click after the user is exposed to the impression for a given unit of time, multiplied by bid B (a CPC bid). The eCPTU for Advertiser C's ad is the probability that an impression will lead the user to take the actions that constitute a conversion for that advertiser after the user is exposed to the impression for a given unit of time, multiplied by bid C (a CPA bid). Of course, the eCPTU for Advertiser D's ad is the bid D, which is a CPTU bid.

Thus, each of the bids from the Advertisers A, B, and C are converted to a common base—that is, eCPTU. The converted bids, along with Advertiser D's bid, which is already a CPTU bid, are therefore utilized to run an auction for a given ad slot. Because, the bids have all been converted to a common base, they can be compared with relative ease. Furthermore, the eCPTU provides a more accurate and intuitive measurement of the value of an ad, as it defines expected cost (or rather, expected revenue from the perspective of the publisher) as a function of actual presentation time of the ad to users.

Thus the true market value of user interactions is better realized. Publishers that have attracted more user time spent will receive a more accurate fair market-share even when they have the same number or a lesser number of page views than other publisher websites. Advertisers also are guaranteed the exposure time of their ads to the users by the nature of these new payment methods, which are based on user-engagement time spent. Advertisers can also be provided with a better sense of budget and spend per time-period so that they can manage online ad campaign spend more effectively. Publishers can also set a fair time-based (or CPTU based) Reserve Price so that their user engagement's market value can be better reflected.

In various embodiments of the invention, systems can be configured to perform GD and NGD advertising in accordance with the methods described herein. For example, the system described with reference to FIG. 1 can be configured to perform GD and/or NGD advertising in accordance with the principles and methods described herein.

With the new payment methods, it is possible to generate new time-based evaluation methods for evaluating the performance/cost of online ad campaigns. For example, the total ad cost of an ad campaign in the NGD market can measure the realized advertising cost and also directly reflect how long the campaign has been exposed to the users (e.g. by a simple formula: cost/price).

A publisher's total revenue can reflect how successfully it has realized the market value of its owned impressions, and how long users have actually spent on their website(s). This also provides an opportunity for a publisher or content-owner to investigate the possible trade-off between user engagement and revenue. The publisher can also forecast potential users' timespent on each of its owned webpages and price them differently. For example, a higher quality property may command a better market price and therefore driving user engagement on such properties will improve the publisher revenue. This is in contrast to the conventional CPM-based model where a publisher may run the risk of having fewer pageviews if each user spends more time on each page because the page quality has improved.

Under the conventional CPM-based model, a publisher is rewarded for increasing the number of pageviews on its webpage, but not necessarily for improving user engagement. In fact, in the case of a publisher who owns multiple webpages, improving engagement on one or more of the webpages may result in fewer pageviews overall, as users dwell for longer periods of time on a given webpage. Under a CPM-based model, this type of situation leads to unfair results, as a webpage having a relatively low viewership but high user engagement will not be fairly compensated under a CPM-based model. However, by performing online advertising in accordance with the time-based methods and systems as are described herein, user engagement can be accounted for by measuring the user dwell time on a webpage, and dwell time can thus be utilized as a basis for determining advertising cost.

One example of a page that may incur a high level of user engagement is the Yahoo! frontpage (www.yahoo.com), which at present includes a stream view feature wherein users may continuously scroll down to view additional content (e.g. article previews or summaries). Thus, users may spend large amounts of time on just one page view. According to the conventional CPM-based approach, a display ad that is visible during a pageview will only register as a single impression regardless of how much time a user spends during that pageview. However, the CPTU-based approach described herein can account for the amount of time spent by the user during the pageview, and thus provides an improved mechanism for handling online advertising.

FIG. 4 illustrates a webpage having various modules for content and advertising, in accordance with an embodiment of the invention. In the illustrated embodiment, the webpage 400 includes various modules 402, 404, 406, 408, 410, 412, 414, 416, 418, 420, and 422. Any of these modules may be defined to include content or advertisements, in accordance with various embodiments of the invention. By way of example, in one embodiment, the module 402 defines a search bar in which a user may enter a search query. In another embodiment, the module 402 defines a banner ad placed at the top of the webpage 400. In one embodiment, the module 404 defines a menu of properties or sections to which the user may navigate from the webpage 400.
